Abstract
The utility model discloses a kind of worm gearing with protective gear, it comprises connected successively motor (1), cycloidal planetary gear speed reducer (2), worm-gear speed reducer (3), moment plate (4) and transfer beam (5), transfer beam (5) is connected with strut (7) with connecting rod (6); Connecting rod (6) below is provided with contiguous block (8), contiguous block (8) is arranged on base (9), between connecting rod (6) and contiguous block (8), tension-compression sensor (10) is installed, tension-compression sensor (10) is connected with force measurement instrument (11).Worm gearing provided by the utility model; reasonable in design; easy to maintenance; stable and reliable for performance; can avoid because of spring, the position limit switch stuck defect that safety protection mechanism cannot normally be worked while causing transshipping of getting rusty, can quantize more accurately to transship limit value, avoid the defect such as misoperation or action delay; Security is better, applies more extensive.
Description
Technical field
The utility model relates to a kind of worm gearing, and particularly one can be monitored Worm Wheel System power value size in real time, and precise quantification overload limit value, has the worm gearing of self-protection function.
Background technique
Worm Wheel System mode, as one of topmost mechanical drive mode instantly, is widely used in, in the transmission system of various machinery, arriving greatly boats and ships, locomotive, industrial automation equipment, little of household electrical appliances common in daily life etc.Therefore, the resist technology of Worm Wheel System mode seems most important.
The protection philosophy of the resist technology of existing Worm Wheel System mode is: in the time of overload; being fixed on moment plate on worm-gear speed reducer rotates because of moment increase; drive strut to move the spring in compression countertorque cover; shake-up is fixed on the lead limit switch on support; send electrical switch amount signal; cut off power mechanism power supply, thereby realize electic protection.
But because lead limit switch is mechanical contact switch; only have the triggering power of contact to reach just meeting trigger switch of a threshold value; like this in real protection; in the time of overload; lead limit switch can not trigger immediately and cut off power mechanism power supply, and can not change and fine adjustment limit-switch positions according to field condition in actual applications.
And the industry equipment of employing Worm Wheel System mode under open-air atmosphere, uses mostly for a long time, the component such as spring, position limit switch get rusty easily stuck, and while causing transshipping, safety protection mechanism cannot normally be worked, and has larger potential safety hazard.
Therefore, necessary on the basis of prior art a kind of structural design of design research and development more reasonable, the worm gearing of self-protection function that what Safety performance was higher have.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art; a kind of reasonable in design, easy to maintenance is provided; stable and reliable for performance; especially can quantize more accurately to transship limit value; and can avoid the defect such as misoperation or action delay, there is the worm gearing of self-protecting function.
Technological scheme: in order to realize above object, the technological scheme that the utility model is taked is:
A kind of worm gearing with protective gear, it comprises motor, the cycloidal planetary gear speed reducer being connected with motor, the worm-gear speed reducer being connected with cycloidal planetary gear speed reducer, the moment plate being connected with worm-gear speed reducer, the transfer beam being connected with moment plate, the connecting rod being connected with transfer beam and strut; Described connecting rod below is provided with contiguous block, and contiguous block is arranged on base, between described connecting rod and contiguous block, tension-compression sensor is installed, and described tension-compression sensor is connected with force measurement instrument.
As preferred version, the above-described worm gearing with protective gear, described tension-compression sensor is 1, is arranged between connecting rod and contiguous block.
As preferred version, the above-described worm gearing with protective gear, the break contact in described force measurement instrument is connected with the control loop of motor.
As preferred version, the above-described worm gearing with protective gear, described force measurement instrument is arranged in electrical control cabinet.
The worm gearing with protective gear described in the utility model; the transmission of power that wherein worm-gear speed reducer produces is to moment plate; moment plate passes torque to strut and connecting rod by transfer beam, and connecting rod is added in active force on tension-compression sensor again.
Pressure value is transferred to the force measurement instrument in regulator cubicle by described tension-compression sensor; in described force measurement instrument, be preset with the power value while being a bit larger tham the normal operation of Worm Wheel System mode equipment; when the power value monitoring is greater than default ceiling value; force measurement instrument can be sent warning; cut off the power supply of motor, protect.
Beneficial effect: compared to the prior art the worm gearing with protective gear described in the utility model has the following advantages:
The worm gearing with protective gear provided by the utility model; reasonable in design, easy to maintenance, stable and reliable for performance; can avoid occurring in prior art because of spring, position limit switch get rusty easily stuck, the defect that while causing transshipping, safety protection mechanism cannot normally be worked.And can quantize more accurately to transship limit value, avoid the defect such as misoperation or action delay, Security is better, applies more extensive.
